int pm_cpu_off | ( | void | ) |
#include <zephyr/drivers/pm_cpu_ops.h>
Power down the calling core.
This call is intended for use in hotplug. A core that is powered down by cpu_off can only be powered up again in response to a cpu_on
The | call does not return when successful |
-ENOTSUP | If the operation is not supported |
#include <zephyr/drivers/pm_cpu_ops.h>
Power up a core.
This call is used to power up cores that either have not yet been booted into the calling supervisory software or have been previously powered down with a cpu_off call
cpuid | CPU id to power on |
entry_point | Address at which the core must commence execution |
0 | on success, a negative errno otherwise |
-ENOTSUP | If the operation is not supported |
